Set the mower higher than the grass. Then clippings won't get shot out onto the road or to the building walls. Anther way that should work is to reverse the direction of the mower blades. Grass cut previously will be sucked back in from your windrows. Mount an offset leaf blower at the discharge chute to blow the clippings back in for further mulching. Turn the deck around to put the discharge chute on the other side. Put a plastic bag over the chute exit and fill it with clippings. Then you can dump them onto the neighbor's property. Buy a goat it's GREEN. Diesel fuel eliminates the need to cut grass. A smart dog can be trained to eat dandelions. Then you won't need weed-B-gon or a mower if you use Roundup !
